Evap of Faint BFP?

Hi guys, I’m 10dpo today and couldn’t resist the temptation to test 🙈 (I know...bold!) but oh how i wish id left it a little later! Driving myself crazy! Im almost certain i see a second line (within the time frame)...I inverted it (even crazier i know) and im sure there is one there. Do evaps normally appear in inverted pics? ALL help and advice appreciated! Here are some pics x
